Forecast Discussion:

The main weather story for this weekend and early next week will be the warm-up! Initially, today (Friday) and Saturday, high temperatures will hold in the mid-70s. A couple of weak, low-pressure disturbances will help in this regard. Then, by Sunday, temperatures are forecast to increase into the upper 70s as high pressure starts to build in. Come Monday, that high pressure will pull the mercury up into the 80s. As for the winds, this afternoon will see some light breezes; but after today, winds will become mostly light.

In regards to PM10 (dust), PM10 will be mostly locally driven, with highest levels expected in the mornings/evenings, when conditions are cool and calm.

Check back on Monday morning for the next Rillito Air Quality Forecast.
